This research was aimed at assessing comprehension, attitudes, and perspectives regarding artificial intelligence (AI) in dentistry. The null hypothesis was a lack of foundational understanding of AI in dentistry. This systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines was conducted in May 2023. The eligibility criteria included cross-sectional studies published in English until July 2023, focusing solely on dentists or dental students. Data on AI knowledge, use, and perceptions were extracted and assessed for bias risk with the Joanna Briggs Institute checklist. Of 408 publications, 22 relevant articles were identified, and 13 studies were included in the review. The average basic AI knowledge score was 58.62 % among dental students and 71.75 % among dentists. More dental students (72.01 %) than dentists (62.60 %) believed in AI's potential for advancing dentistry. Thorough AI instruction in dental schools and continuing education programs for practitioners are urgently needed to maximize AI's potential benefits in dentistry. An integrated PhD program could drive revolutionary discoveries and improve patient care globally. Embracing AI with informed understanding and training will position dental professionals at the forefront of technological advancements in the field.

Background: Pain and inflammation are common problems after the third molar surgery. The purpose of this study was to compare the effect of ibuprofen and intra-muscular injection or the intra-socket placement of dexamethasone on pain, swelling, and trismus after the extraction of impacted third molar. Methods: In this triple-blind randomized clinical trial study, 72 eligible patients were randomly divided into four groups of 18 subjects. The groups received dexamethasone powder (4 mg) inside the alveolar socket immediately before flap suturing, injection in the masseter muscle (4 mg/1 mL) immediately after the suture, the ibuprofen tablet from an hour before the surgery (400 mg every 6 hours for 1 day), and placebo. Three parameters of pain severity, swelling, and trismus were evaluated on the second and seventh days after the surgery. Data were analyzed using SPSS 17. Qualitative and quantitative data were expressed as a percentage and mean ± standard deviation, respectively. Chi-square, one-way analysis of variance (ANOVA) and, if necessary, the least significant difference tests were used for inter-group comparison. The findings were significant at P<0.05 Results: Dexamethasone groups had significantly lower pain severity (second and seventh days), swelling (second day), and maximum mouth opening (MMO, alveolar socket: second and seventh days, masseter: second day) in comparison to the other groups (P<0.05). The ibuprofen group had significantly lower levels of pain (second and 7th days) and swelling (second day) in comparison to the control group (P<0.05). There was no significant difference between dexamethasone groups in any measurement for pain, swelling, and MMO. Conclusions: The findings of this study suggest that the intra-oral administration of dexamethasone may have a better effect on pain, swelling, and trismus compared to ibuprofen and has no placebo effect.

Background: In recent years, the use of mouthwashes containing green tea (GT) extract has been reported to prevent tooth decay. In laboratory studies, GT has been shown to be effective in controlling dental plaque and erosion. The aim of this review study was to evaluate the effectiveness of GT extract in controlling tooth decay and erosion in randomized clinical trials. Methods: By searching related keywords in the Scopus, PubMed, and WOS (Web of Science) databases, as well as searching for related studies in the Google Scholar database randomized clinical trial ( RCT) studies published in English by the end of 2019 were extracted. Then, eligible studies were carefully reviewed and the required data were extracted. Results: A total of 12 eligible studies were included in the study. The inclusion criteria of the study were human RCT studies, English language, and GT intervention. The exclusion criteria of the study were lack of negative (placebo) or positive control group, studies examining the effect of GT derivatives, oral diseases such as periodontal disease, people undergoing orthodontic treatment, use of antibiotics at least two weeks before the study, incomplete methodology, defects in the results, and lack of access to the full text of articles. The number of subjects was 246 in the GT group, 157 in the placebo group, and 132 in the positive control group (sodium fluoride, chlorhexidine, neem extract, and probiotic). Eleven studies used GT mouthwash and one study used toothpaste containing GT extract. In studies with placebo, GT showed a significantly better effect on dental plaque, oral pH, modulation of dental erosion, and reduction of the number salivary S. mutans and lactobacilli colonies. Additionally, GT had a similar and comparable effect to positive control groups in modulating the above-mentioned indices. Conclusion: GT extract can show anti-cariogenic and anti-erosive effects. Larger randomized clinical trials are needed to support our findings.
